Title: Wheel-spin control for vehicle -  is blocked above preset road speed using inhibit switch
Inventor: STERLER GEORG DIPL ING
IPC: B60T8/175
Filed: 1990-09-14
Abstract: The driven wheels (VR, VL) are braked via brake control valves (9, 10) in the ABS circuit. These valves also connect the brakes to the servo pressure (13) for wheelspin control. To prevent instability at higher road speeds, the electric supply to the two valves is switched off by a control switch (29) controlled by a road speed sensor (30). Above a set speed, the wheelspin control is blocked. - Sensors on each wheel provide the wheel speed signals. A processor (18) generates the wheelspin control signal as well as the ABS signals. The separate road speed sensor (30) provides an independent control for the wheelspin.

Patent DE-4118782-A1 (DE)
Inventor: SOMMER FRANK-UWE
IPC: E05F15/47
Filed: 1991-06-07
Abstract: A safety system for a passage closure member, such as a gate, door, window, sliding roof or the like, has a drive whose maximal admissible strain value is adjustable and a control device by means of which the drive can be switched off. When the drive is switched off because the maximal admissible strain value has been attained, a signal S2 at the moment in time T2 is transmitted to the control device. In the area of the pressing and/or closing edge of the closure member is arranged a sensor that transmits a signal S1 at the moment in time T1 when an obstacle occurs. The control device calculates, when the maximal admissible strain value is attained, the differential value between the moments in time  DELTA  Treal=T2-T1. The control device compares the value  DELTA  Treal with a predetermined value Tpredet., and when  DELTA  Treal is higher than DELTA  Tpredet., the direction of movement of the closure member is changed.

Abstract: In sheet-fed rotary printing machines for perfecting, a double gearwheel with a coupling device is provided in the gear train. Said coupling device is to be made to function automatically whilst the double gearwheel is to remain simple in terms of construction and not additionally loaded in terms of weight. 
<??>The coupling device consists of a substantially two-part annular mechanism (36, 37) which is attached movably to the machine frame (26). Together with an outer ring (37) an inner ring (36) forms a compression space which is pressurised with hydraulic fluid for uncoupling. In this process, the rings (36, 37) are pressed apart until the outer ring (37) strikes against a clamping device for the gearwheel ring on the double gearwheel and the inner ring (36) against an unlocking element (39) on the main gearwheel and the clamping force of the clamping device on the gearwheel ring is reduced. The forces to be applied are conducted inside the double gearwheel. For renewed clamping, the annular space is again made pressureless. In the state of rest, the coupling device does not touch the gearwheel.
